• Quiets noisy transmissions and protects heavy-duty components
• Enhances film strength for long-lasting engine protection

Exceptional film strength withstands high temperatures and pressures. Improves overall drive train performance across diverse vehicles. Boosts MPG and power by minimizing friction and wear.

Best as an additive, not a standalone oil replacement. May require testing in very cold climates for optimal flow. Primarily benefits older or high-mileage equipment.

Lucas High Mileage Oil Stabilizer is a 100% petroleum additive that lubricates engine internals to minimize wear and eliminate noise, emissions, and oil consumption in worn engines. High-mileage vehicle owners should buy it to extend engine life without full oil changes.

• Minimizes internal engine wear for extended lifespan
• Eliminates annoying engine noise from wear
• Reduces harmful emissions in older engines
• Cuts excessive oil consumption significantly
• Provides superior lubrication for all engine parts

Comprehensive lubrication reduces friction and wear. Targets common issues in worn engines like noise and consumption. Easy to add to existing motor or transmission oil.

Best for high-mileage or worn engines, less impact on new ones. Acts as additive only, not a full oil replacement. Effectiveness depends on engine condition severity.

Lucas Oil 10001 Heavy Duty Oil Stabilizer is a pure petroleum supplement that eliminates dry starts and minimizes friction, heat, and wear in engines, transmissions, and differentials. Heavy-duty truck owners and high-performance enthusiasts should buy it to enhance lubrication and reduce oil consumption.

• Eliminates dry starts for smoother engine operation
• Minimizes friction, heat, and wear to extend engine life
• Reduces oil consumption and lowers operating temperatures
• Controls noise in manual transmissions and differentials
• Enhances lubrication for peak performance under demanding conditions

Proven to quiet engine noise and reduce wear. Improves overall lubrication and efficiency. Compatible with heavy-duty and high-performance applications.

May slightly thicken oil viscosity. Results can vary based on engine condition. Not a replacement for regular maintenance.
